I don't know. I had no problems with kinking, and I think the stuff I used was thick walled. They make springs you slip over the tubing to bend it without kinking, but I did not need it. The more copper, the less resistance, so try the thick stuff.

Mine will be 4" in diameter and 3" in diameter. Which tubing is best (no kink) thick or thin?
